iPhone 4S in App purchase and we continually get "Could not connect to iTunes"
My son has an iPhone 4S we just setup. We got him and AppleID and put in the necessary credit card information. He is trying to make an in App purchase and we continually get "Could not connect to iTunes" as an error. It works from other iOS devices. We've done the trouble shooting listed online. We have another iPhone 4S with a different Applie ID that connects and bills just fine. The only difference I've noticed is that the other son's account shows our PC and both of his iOS devices listed as authorized devices for his account but this Apple ID doesn't like his phone as an authorized device. I don't know why when we've put in all of the info on the phone and it seems to be accepted ok.
iPhone 4S, iOS 7.0.4
